Strange guest in my solarium cabin!

Now that's something! I wanted to go to the solarium again for ages, but I got so warm in there that I went out a little earlier..... And there he was! In my cubicle! The young guy who was previously sitting in the waiting area, smiling nicely at me and waiting for his solo to become free.... and now he was standing in front of me! Pants pulled down and his hard cock in his hand! .... I must have forgotten to lock up!
